Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 476SML016MD5 is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Capacitance: 47 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can - SMD (exact match required)
• Physical Dimensions: 0.197" Dia (5.00mm) × 0.217" Height (5.50mm) (exact match required)
• Surface Mount Land Size: 0.209" L × 0.209" W (5.30mm × 5.30mm) (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Lifetime @ Temperature: 2000 Hrs @ 85°C (exact match required)
• Polarization: Polar (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The two substitute parts identified—RV5-16V470ME55U-R2 (Elna America) and UWR1C470MCL1GB (Nichicon)—satisfy all critical matching parameters and are therefore electrically and mechanically interchangeable with the 476SML016MD5.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: 476SML016MD5 (Cornell Dubilier / Illinois Capacitor)

The 476SML016MD5 remains the preferred choice for new designs. This part is in active production status, ensuring long-term availability and supply chain stability. It provides the lowest ESR at 7.055 Ohm @ 120 Hz among the available options, which is advantageous for applications requiring minimal impedance. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1).

Secondary Selection: RV5-16V470ME55U-R2 (Elna America)

The RV5-16V470ME55U-R2 is designated as "Not For New Designs" and should be used only for legacy system maintenance or replacement applications. This part maintains full electrical and mechanical compatibility with the 476SML016MD5. It is supplied in Tape & Reel packaging with 6630 pieces in inventory. The ripple current performance at 100 kHz is 67.5 mA, which is lower than the primary part.

Tertiary Selection: UWR1C470MCL1GB (Nichicon)

The UWR1C470MCL1GB is classified as "Obsolete" and should be used only when no other alternatives are available for critical legacy system repairs. This part is supplied in Tape & Reel packaging with 6961 pieces in inventory. The ripple current performance at 10 kHz is 87 mA, which exceeds both the primary and secondary options. This part is not suitable for new design implementations.

All three parts are ROHS3 compliant, REACH unaffected, and carry the same ECCN (EAR99) and HTSUS (8532.22.0020) classifications.

Frequently Asked Questions (FAQ)

Q: Can the RV5-16V470ME55U-R2 be used as a direct replacement for the 476SML016MD5?

A: Yes. The RV5-16V470ME55U-R2 meets all critical electrical and mechanical parameters required for direct substitution. Both parts share identical capacitance (47 µF), voltage rating (16 V), tolerance (±20%), physical dimensions (0.197" Dia × 0.217" Height), surface mount land size (0.209" L × 0.209" W), operating temperature range (-40°C to 85°C), and lifetime rating (2000 Hrs @ 85°C). However, the RV5-16V470ME55U-R2 is designated "Not For New Designs," limiting its use to legacy applications.

Q: What is the difference between the ESR specifications of these parts?

A: The 476SML016MD5 specifies an ESR of 7.055 Ohm @ 120 Hz. The RV5-16V470ME55U-R2 and UWR1C470MCL1GB do not provide ESR specifications in their datasheets. ESR values are important for applications sensitive to impedance characteristics, particularly in power supply filtering and high-frequency circuits.

Q: Are there packaging differences between these substitute parts?

A: The 476SML016MD5 packaging format is not specified in the provided data. Both substitute parts (RV5-16V470ME55U-R2 and UWR1C470MCL1GB) are supplied in Tape & Reel (TR) packaging. Verify packaging requirements for your specific assembly process before selection.

Q: Can the UWR1C470MCL1GB be used in new designs?

A: No. The UWR1C470MCL1GB is classified as "Obsolete" and is not suitable for new design implementations. This part should be used only for repair and maintenance of existing systems where no other alternatives are available.

Q: What are the ripple current differences between these parts?

A: The 476SML016MD5 supports 52 mA @ 120 Hz and 78 mA @ 100 kHz. The RV5-16V470ME55U-R2 supports 52 mA @ 120 Hz and 67.5 mA @ 100 kHz. The UWR1C470MCL1GB supports 58 mA @ 120 Hz and 87 mA @ 10 kHz. Applications requiring specific ripple current performance should verify these specifications against circuit requirements.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts—476SML016MD5, RV5-16V470ME55U-R2, and UWR1C470MCL1GB—are ROHS3 compliant and carry unlimited moisture sensitivity rating (MSL 1). All parts are REACH unaffected and classified under ECCN EAR99 and HTSUS 8532.22.0020.

Q: What inventory levels are available for each part?

A: The 476SML016MD5 has 660 pieces in stock. The RV5-16V470ME55U-R2 has 6630 pieces in stock. The UWR1C470MCL1GB has 6961 pieces in stock. Inventory levels should be verified at the time of procurement.
